When we used the parallel port as an IO device for the Lorraine (the Amiga
prototype), we connected it's strobe & acknowledge to acknowledge & strobe
of our Sage code development machine.  Of course, we had fewer machines
than Matt in those days, so we were not trying to network it :-).

Did you consider tying the flag input to D5?  If the network is only
sporatically busy, this would allow an interrupt wake up mechanism
for prospective clients instead of having them poll it.  That would
contribute to the loading problem, though, for which I've no spec to
refer to.
